Frequently Asked Questions

What range of currents can these instruments measure?
They're built for low-current measurement from detectors, typically down into the picoamp range. Exact ranges vary by model; see the specific product's datasheet or contact us for your application's requirements.
What's the difference between current measurement and charge measurement?
Both types of instruments can technically measure current and charge, since charge is just current integrated over time. In practice, though, each is built and optimized for one measurement over the other.
When should I choose a current-measurement instrument instead of a charge-measurement instrument?
Current-measurement instruments are intrinsically faster, so they're the better choice when data speed is the priority. If instead you need to resolve ultra-low currents or charges as precisely as possible, a charge-measurement instrument is usually the better fit, since charge-measurement instruments have less intrinsic noise.
What types of detectors typically pair with current-measurement instruments?
Detectors that produce a continuous or pulsed current in response to radiation, particles, or light, such as ionization chambers, photodiodes, and similar sensors.
Do these instruments support both continuous and pulsed signals?
Many are designed to handle both, but the right configuration depends on your signal characteristics and timing requirements. Reach out and we can help match an instrument to your application.
